5D's Ride 64: "Rise Above!!" 172.0 172.1 Yu-Gi-Oh
Heres how it plays out: You are required to have The Gitrog Monster out, Dakmor Salvage in hand and more than 7 cards in hand total At the end of the turn, discard down to hand size, discarding Dakmor Salvage This gives you a draw card trigger from The Gitrog Monster Priority passes to opponents On resolution of the draw trigger, replace this with the dredge from Dakmor Salvage, milling 2 cards and returning Dakmor Salvage to hand As it is still the cleanup step you still need to discard down to 7 cards in hand, again discarding Dakmor Salvage and repeating the combo above on a loop The idea is you loop this to fill your graveyard and try to win from there
You do not need The First Chapter, Rise of the Floodborn, Into the Inklands, or Ursulas Return to play the game
You usually only see this sort of mechanic on green cards, but since its colorless, it can function in all sorts of decks perhaps best in five-colors, where you need the extra mana ramp
